Also cupra seat tdi. ('54 plate) Door wont shut! Well it will and swings back open. Passenger side door. On and off problem for over year. If door was locked that would hold shut and work fine again. Now got a piece of string keeping it shut!!!Think it might need lubing especially as new £85.18 plus VAT. Will golf mech fit? Thanks

Hi, spose you could say no boost!!! What can be done to the solenoid valve to get working properly (OR replace) or could it be something else? Wots with the terminal 30, low voltage? Is there anyone local to Gt yarmouth that could pop round and have a look? Thanks again.

Original poster - sounds like a boost leak through that valve. Suggest you replace it if you haven';t already mate.
